RESUMO
Introduction: Small bowel obstruction (SBO) is known as a common cause of acute abdominal complaints in the emergency department (ED). The modality of choice for the diagnosis of SBO has not yet been established. This systematic review and meta-analysis aimed to investigate the accuracy of ultrasonography for the diagnosis of SBO. Methods: Systematic search was performed on five electronic databases including Medline, Scopus, Web of Sciences, Embase, and Cochrane Library, and the retrieval period was from the inception of each database to November 2023. The quality of the included studies were investigated using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). The pooled values of diagnostic characteristics for ultrasonography were estimated using meta-Disc and Stata statistical software. Results: Twenty-one studies with a total of 1977 patients were included in the meta-analysis. The pooled estimate for sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary ROC curve of ultrasonography for diagnosing SBO were 0.93 (95% CI: 0.91-0.95), 0.8 (95% CI: 0.77-0.83), 5.69 (95% CI: 3.64-8.89), 0.1 (95% CI: 0.07-0.16), 83.51 (95% CI: 18.12-182.91) and 0.96, respectively. Conclusion: The findings of this meta-analysis showed that the utilization of ultrasonography holds promise as a diagnostic imaging for SBO with high accuracy. However, additional worldwide studies are essential to get more evidence on the value of ultrasonography for the diagnosis of SBO.
RESUMO
INTRODUCTION: Post-dural puncture headache (PDPH) is one of the most common problems of cesarean section. The present study aimed to evaluate the effect of pregabalin on PDPH among patients undergoing elective cesarean section. MATERIALS AND METHODS: This double-blind clinical trial was performed on 136 patients undergoing elective cesarean section referred to Shahid Motahari Teaching Hospital in Urmia in northwestern Iran from February 1 to December 20, 2020. Patients were selected by convenience sampling method and randomly divided into two groups of intervention and control (N = 68 people each group). The presence of PDPH and its severity were recorded in the checklist based on the VAS, and conventional treatments were prescribed in the case of occurrence of the PDPH. The PDPH severity was also assessed by the patient using the 10-cm Visual Analog Scale (VAS). RESULTS: The mean age of participants was 27.82 years. A total of 29 people suffered from hypotension. Regarding pain severity, the mean pain score in the intervention group was significantly lower than the control group (p = 0.01). Results also showed that the frequency of PDPH in the intervention group was significantly lower than the placebo group (4.4% vs. 11.8%; p = 0.019). There was no significant difference between intervention and control groups in terms of demographic characteristics (p > 0.05). CONCLUSION: Results of the present study showed the use of oral pregabalin at night before spinal anesthesia in patients undergoing elective cesarean(C-) section had a preventive effect on the severity and incidence of PDPH.
RESUMO
INTRODUCTION: Following advances of Intensive Care medicine and widespread administration of mechanical ventilation, tracheostomy has become one of the indispensable surgical procedures. During this research we tried to assess and compare two main strategies for doing tracheostomy: Surgically Created Tracheostomy (SCT) and Percutaneous Dilatational Tracheostomy (PDT). METHODS: In a randomized clinical trial, 60 cases of patients who were admitted in Intensive Care Unit (ICU) and needed tracheostomy during their stay were enrolled. Patients were randomly divided into two groups. SCT technique was considered for the first group and PDT for the second one. Demographic characteristics, associated and underlying diseases, type and duration of procedure, duration of receiving mechanical ventilation and ICU stay, expenses and complications of tracheostomy including bleeding, subcutaneous emphysema, pneumothorax, stomal infection and airway loss were all recorded during study and compared between both groups. RESULTS: There were significant differences between two groups of patients in terms of duration of receiving mechanical ventilation (P=0.04), duration of tracheostomy procedure (P=0.001) and procedure expenses (P=0.04). There was no significant difference between two groups in terms of age and gender of patients, duration of ICU stay and complications of tracheostomy including copious bleeding, stomal infection, subcutaneous emphysema and airway. CONCLUSION: According to the results of our study and similar researches, it can be concluded that PDT can be considered as the preferred procedure in cautiously selected patients during their ICU stay.
